I am resteeming now because for curation and contests it is very challenging when working through copying and pasting. More discussion about plagiarism and especially alternatives may help. On my supernatural writing contest we need to use copyscape and require many words to minimize this and with photography it must be a nightmare! We also do not benefit from giving those of us that copy images elsewhere rewards.
I also hope resteeming this because I hope sharing this post leads to some more genuine entries because we do want to reward those of us that are creating original artwork on STeem!
Thanks for your support on this issue, @jerrybanfield! I have an idea, though I'm not a programmer to implement it: it would be extremely useful for those running contests to have a quicker method of initiating a reverse image search - perhaps a page that can grab the image URLs from post comments or tagged blog posts and input them into a clickable link to an RIS page like TinEye, to make it easier to reverse search a bunch of photos all at once. Or a browser extension that adds an RIS link to the right-click menu.
The RIS is not a perfect way to catch plagiarists, since many photos are legitimately scattered all over the internet already, even though they ARE our photos, but it's the best first step to catching people out, and it's clunky right now to have to copy-paste every image URL into a separate webpage.
